OutlierDetection class
Settings controlling the eviction of unhealthy hosts from the load balancing pool for the backend service.
Constructors
- OutlierDetection({Duration? baseEjectionTime, int? consecutiveErrors, int? consecutiveGatewayFailure, int? enforcingConsecutiveErrors, int? enforcingConsecutiveGatewayFailure, int? enforcingSuccessRate, Duration? interval, int? maxEjectionPercent, int? successRateMinimumHosts, int? successRateRequestVolume, int? successRateStdevFactor})
- OutlierDetection.fromJson(Map json_)
Properties
- baseEjectionTime ↔ Duration?
-
The base time that a backend endpoint is ejected for.
getter/setter pair
- consecutiveErrors ↔ int?
-
Number of consecutive errors before a backend endpoint is ejected from the
load balancing pool.
getter/setter pair
- consecutiveGatewayFailure ↔ int?
-
The number of consecutive gateway failures (502, 503, 504 status or
connection errors that are mapped to one of those status codes) before a
consecutive gateway failure ejection occurs.
getter/setter pair
- enforcingConsecutiveErrors ↔ int?
-
The percentage chance that a backend endpoint will be ejected when an
outlier status is detected through consecutive 5xx.
getter/setter pair
- enforcingConsecutiveGatewayFailure ↔ int?
-
The percentage chance that a backend endpoint will be ejected when an
outlier status is detected through consecutive gateway failures.
getter/setter pair
- enforcingSuccessRate ↔ int?
-
The percentage chance that a backend endpoint will be ejected when an
outlier status is detected through success rate statistics.
getter/setter pair
- hashCode → int
-
The hash code for this object.
no setterinherited
- interval ↔ Duration?
-
Time interval between ejection analysis sweeps.
getter/setter pair
- maxEjectionPercent ↔ int?
-
Maximum percentage of backend endpoints in the load balancing pool for the
backend service that can be ejected if the ejection conditions are met.
Defaults to 50%.
getter/setter pair
- runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
- successRateMinimumHosts ↔ int?
-
The number of backend endpoints in the load balancing pool that must have
enough request volume to detect success rate outliers.
getter/setter pair
- successRateRequestVolume ↔ int?
-
The minimum number of total requests that must be collected in one
interval
(as defined by the interval duration above) to include this backend
endpoint in success rate based outlier detection.
getter/setter pair
- successRateStdevFactor ↔ int?
-
This factor is used to determine the ejection threshold for success rate
outlier ejection.
